others, The pileus is attached by a grayish villosity. In drying it 
sometimes becomes nearly black. It is then so small and shriveled 
that it is easily overlooked. 
CLAUDOPUS, Smith. 
Pileus eccentric, lateral or’resupinate. Spores pinkish. 
The species of this genus were formerly distributed among the Pleu- 
roti and Crepidoti, which they resemble in all respects except in the 
‘color of the spores. The genus at first was made to include species 
with lilac-colored ag well as pink Spores, but Professor Fries limited it 
to species with pink spores. In this sense we have taken it. The spores 
in some species are even, in others rough or angulated. The stem is 
either entirely wanting or is very short and inconspicuous, a charac- 
ter indicated by the generic name. The pileus is often resupinate and 
attached by a dorsal point when young, but it becomes reflexed with 
age. The species are few and infrequent. All inhabit decaying 
wood,

Agaricus nidulans, Pers, 
Pileus one to three inches broad, sessile or rarely narrowed behind 
into a short stem-like base, often imbricated, suborbicular dimidiate 
or reniform, tomentose, somewhat strigose-hairy or squamulose-hairy 
toward the margin, yellow or buff color, the margin at first involute; 
lamellee rather broad, moderately close or subdistant, erange-yellow ; 
spores even, slightly curved, .00025 to .0003 in. long, about half as 
broad, delicate pink. 
Decaying wood. Sandlake, Catskill and Adirondack mountains. 
Autumn, 
This fungus was placed by Fries among the Pleuroti, and in this he 
has been followed by most ‘authors. But the spores have a delicate 
pink color closely resembling that of the young lamelle of the com- 
mon mushroom, Agaricus campestris. We have, therefore, placed it 
among the Claudopodes, where Fries himself has suggested it should 
be placed if removed at all from Pleurotus. Our plant has sometimes 
_ been referred to Panus dorsalis, Bose., but with the description of 
that species. it does not well agree. The tawny color, spathulate 
pileus, paler floccose scales, short lateral stem and decurrent lamellee 
ascribed to that species are not well shown by our plant. The sub- 
stance of the pileus, though rather tenacious and persistent, can 
scarcely be called coriaceous. The flesh is white or pale yellow. The 
tomentum of the pileus is often matted in small tufts and intermingled 
with coarse hairs, especially toward the margin, This gives a squa-
